For fast, reliable eluent preparation, the ready-to-dilute Thermo Scientific™ Dionex™ AS22 Eluent Concentrate; Sodium Carbonate/Bicarbonate Concentrate will save you time and eliminate potential contamination and preparation error. For use with Dionex™ IonPac™ AS22 columns, simply prepare eluent by dissolving the concentrate in deionized water. The 250mL of 100x concentrate is made with only high purity, reagent grade chemicals and water (18 MO-cm) and quality checked for ionic contamination. Concentrations of 0.45M carbonate and 0.14M bicarbonate are verified.

• The IonPac™ AS22 Eluent Concentrate is available for anion applications as a 100X concentrate containing 0.45M carbonate/0.14M bicarbonate Recommended for fast, reliable eluent preparation
• Prepared by the dissolution of high-purity chemicals in >18.2MΩcm deionized water, which was tested by ion chromatography for ionic contaminants
• Bottle label states the nominal concentration value for informational purposes only
• Actual concentration is within ±2.5% and was determined by one or more proven reliable methods of analysis such as ion chromatography, UV spectrophotometry (using NIST or USP Reference Material where applicable), titration (using NIST Reference Material) and gravimetric preparation
